• The N54 finally comes into its own - Vargas Turbo Tech Stage 3 N54 (335/135) twin turbocharger upgrade sets new N54 horsepower record with 693 wheel dyno

      Congratulations are in order to Vargas Turbo Tech as well as Cobb tuning and ProTuning Freaks for raising the bar as to what the BMW N54 inline-6 twin turbo motor is capable of. There are two platform records here the first of which it is important to note was achieved without methanol injection. There are certain tuners on the N54 platform that mask their ability to upgrade and control the stock fueling system and any fueling issues are "solved" by dumping in a ton of methanol.

      Well, with no meth and the cars own fuel system (with High Pressure Fuel Pump tweaks courtesy of Vargas Turbo Tech) responsible for all the fueling 673 wheel horsepower was achieved in STD correction on a Dynojet. That is a record for horsepower on the platform without methanol injection and was done with a blend of MS109 fuel and 93 octane.

      Meth injection was then added and the figures rose to 693 wheel horsepower. If more time was available for the parties involved including Josh at Cobb as well as Jake and Dzeeno at ProTuning Freaks the 700 wheel barrier likely would have been crossed. This will happen sooner rather than later now but this is still a major milestone and a new era the N54 is entering. The motor is finally starting to mature and although it is not on a comparable power level yet with the top BMW aftermarket options this is a huge step step forward for a platform that spent considerable time in limbo due to fueling and tuning issues.

      It must be satisfying for all involved especially Vargas Turbo who was doubted by many early on due to being a fresh entrant on the N54 tuning scene with many fanboys blindly following another tuner providing a turbo upgrade. Vargas Turbo Tech, Cobb, and PTF have surprisingly quickly surpassed the results from a competing turbo kit that uses a single turbo setup and have done so without relying on meth injection band-aids. A true fueling upgrade is here as well as a turbo upgrade making some serious power and setting the standard.

      Congratulations and much respect to all the parties involved, dyno graphs and videos are below.

        Awesome, congrats! It holds the power straight to 7200rpm too. Can't wait to see some e85 numbers and driving video with a chick in a bikini in the passenger seat. For science.

        Also, @govr46 & @VargasTurboTech -- When does the street testing begin?? I'm sure everybody is really excited to see how all this power translates into street performance (60-130s, 0-60 & 1/4 mile times)

        They were running the Walbro in parallel with the OEM, IIRC.
        This is correct, never a single LPFP flow issue. We have had some pick up issues, the real estate in that bucket is tight and it seems the bucket might not be able to hold enough fuel nor fill fast enough to keep up with both pumps when the tank gets low. I will be pulling it and seeing what I can find.

        I have a feeling there will be quite a few Stage 3 kit order upgrades from Stage 2.

        Looking good! FYI, MS109 has an octane rating of 105 (R+M/2) so you actually had a lower octane than what is calculated, around 96.5 if my math is correct.

        Hey man, thanks for the compliment. I actually didn't know that. But thats even better news. Just raises the ceiling for us even higher once we go straight 109 or E85...Click here to enlarge

        Anyone know if this is the highest recorded dyno pull for an N54? I have never seen higher. If there is one please let me know.

        I'm looking into that right now and yep, sure looks like it. Also obviously the highest dyno pull without meth.
